Augustin ISAAC - ISO pedals c.1950

Amazing and exceedingly rare Pithioud bicycle equiped with ISO pedals, requiring a special frame with very high bottom bracket. The idea is to have a smaller lighter frame, and to remove the "dead spot" of normal pedaling. These pedals were not just a gimmick, they won important races at the time, and were used by important makers like Charrel, Terrot, Reyhand.
